（四）创建django项目，创建数据库，测试运行

django-admin startproject mysite

python manage.py runserver

激活虚拟环境
env_mysite\scripts\activate

进入项目所在路径
cd xxx

安装
pip install pymysql

DATABASES = {
    ‘default‘: {
        ‘ENGINE‘: ‘django.db.backends.mysql‘,
        ‘OPTIONS‘: {‘read_default_file‘: ‘C:/Users/xxx/xxx/xxx/my.cnf‘},
    }
}

[client]
database = dmysql
user = root
password = root
default-character-set = utf8
HOST = 127.0.0.1
PORT = 3306

import pymysql
pymysql.install_as_MySQLdb()

from django.db import models
# Create your models here.
class user_info(models.Model):
    username = models.CharField(max_length=30)
    upassword = models.CharField(max_length=30)

python manage.py check    检查框架

python manage.py makemigrations  生成迁移文件 

python manage.py migrate
